Blue Origin completes first static fire test of New Glenn upper stage
Blue Origin yesterday successfully conducted a 15 second static fire test of the upper stage of its orbital New Glenn rocket.
The hotfire lasted 15 seconds and marked the first time we operated the vehicle as an integrated system. The purpose of the hotfire test was to validate interactions between the subsystems on the second stage, its two BE-3U engines, and the ground control systems.
Additionally, we demonstrated its three key systems, including: the tank pressurization control system, which uses helium to pressurize the liquid hydrogen and liquid oxygen tanks during flight; the thrust vector control system, which gimbals the engines and steers the rocket during flight; and validated the start-up and shut-down sequences for the BE-3U systems, which can be restarted up to three times during a mission.
In addition to testing our flight hardware, this hotfire test was also an opportunity for the launch operations team to practice launch day procedures on console and verify timing for a number of critical operations.
An actual launch date has not been announced. Previously New Glenn was to carry two Mars orbiters for NASA and launch by October 21, 2024 at the latest. Because of doubts the company could meet that data, NASA pulled the satellites from the rocket.
Prior to launch the company still has to do a full static fire test of the rocket’s first stage. Though company officials have said this would happen “very soon,” no date has been announced for the test.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
